The real lottery in life is being born. The chances are so slim. Think about it, every little decisions made by your ancestors where crucial to you being alive today. The day I realised this about my life, is the day I realised I should be grateful for my life. We are not dealt the same cards infortunetly but we have to do our best with what we got. So cheers to you guys, it's been an honor to be alive at the same time as you guys.

I think this is the only video on YouTube that really talks about the development of the Zygote. Thanks for the video!

Alicia Silverstone telling me about fertilization

What about week 2 I'm between 12 to 14 days feeling warmth and things going on too

[christopherihendu]

This is a detailed explanation. Thank you.

The sperm does not do the job of "penetrating", the oocyte has to let it in. Penetrating is such an old term... even after researchers have found that is the case, people still use penetrate...

[alexisreyes]

wow thanks for the video, I have learned a lot about the embryonic development and implantion

[VijayaLakshmi-prdv]

U said that after fertilization of egg and sperm it goes to mitosis Pls correct goes to 2nd meiotic division and it divides to 4 haploid cells that is called as 4 celled stage

[MrCuddlyable]

What she calls uterine tubes are named Fallopian Tubes after the anatomist Gabriele Falloppio.

I have a question in the last part under fetal development, when you say 3 weeks, 5 weeks of the embryo. Do you mean it is from 3 weeks or 5 weeks from fertilization or 3 weeks from 5 weeks from Last Menstrual Period date??

very intresting n simply understandable videos ever...thanks

Only head part enter in secondary oocyte. More precisely only genetic material and centrioles.

[MJ-urbz]

thanks for the video. it helps me to understand better fertilization process

[SherineYousery]

Very good and simple :)
Suits high school level though, not Med School.

[Mental-Maniac]

So I have a question? what if a woman takes on 2 deferent sperm cells and only takes on one cell of the father. what happens to the other sperm cell and does not produce a twins set

[lisabjurstrom]

Uterine tubes? Are you sure they are called that? Cause i heard they are called FALLOPIAN TUBES.
